Side effects and other unwanted things are generally avoided. A side effect of medicine can take place due to several reasons like the diet, alcohol consumption, body suitability and at last combining with other medicines. A combination has both perspectives i.e a combination can create more effective medicine or else drop the effect of one medicine causing side effects. Such Combination needs to be avoided especially when you are your own.

Gabapentin is an anti-epileptic drug called anticonvulsant. Gabapentin affects chemicals in the body that cause seizures and some types of pain. It belongs to a drug class called Gamma-aminobutyric acid analogs. The most common brand of Gabapentin generic is Neurontin.

Robaxin is a muscle-relaxing drug and belongs to a drug class called Skeletal muscle relaxants. It works by blocking nerve impulses and the pain signals sent to your brain. The generic name for Robaxin is Methocarbamol.

You can order Robaxin online by visiting a certified online pharmacy, but it is better to take any medications with a doctor’s advice.

Medical Professionals won’t suggest you take Gabapentin and Robaxin together. Gabapentin is a pain killer, while Robaxin is a muscle relaxer. Taking these two medications together might increase the side effects caused by them.

You can purchase both the medications only with a prescription. However, if the doctor feels the need to, there can be exceptions made to the use of Gabapentin and Robaxin together.

Let’s understand it through a proof.

The Proof Center

The University of Texas Medical Branch studied multimodal pain pump groups with the added use of Gabapentin and Robaxin together for post-operative scoliosis surgery. We believe it is the first study that examined the use of Gabapentin and Robaxin together for pain management.

Method: Gabapentin and Robaxin were both given orally. Gabapentin 3 times a day and Robaxin (Methocarbamol) every 6 hours if the patient weighs over 33 kg. The endpoints were analyzed for the length of stay in the hospital, post-operative gastrointestinal retention, and infection rate. The study concluded in showing improvements in pain management by the use of elastomeric pumps post-operation. The addition of Gabapentin and Robaxin showed a trend towards further improvements in the patients (Carlson, J.D., Peloquin, J. and Falowski, S.M., 2016).

There is not much data on the use of Gabapentin and Robaxin when used together. It is typically advised not to use them together as there can be adverse side effects; however, it can be used under very specific circumstances if the doctor as per his or her knowledge feels right. (Lee, T.J., 2010).

What Happens When You Take Gabapentin And Robaxin Together?

As the study suggests that it is not recommended to consume gabapentin and robaxin due to its adverse side effects. They both are highly interactive enough to create unwanted effects.

Using Gabapentin and Robaxin together may increase the side effects such as dizziness, drowsiness, difficulty concentrating, and confusion. Some people may find a problem in judgment, motor coordination, and impairment in thinking, especially the elderly. 

Try to avoid using Robaxin with alcohol during the treatment of these medications. Also, you must try to avoid activities that require mental alertness, such as using heavy machinery or driving a vehicle, until you understand how the medicine affects you.

How Will You Manage The Side Effects?

Accidents happen or mistakes are also caused due to human errors but there should be a way out to cope up with the issue .

Patients should be carefully monitored for excessive or prolonged CNS or respiratory depression. Proper dosage titration may be required during the time of the treatment. People who need help or support to walk should be counseled to avoid hazardous activities which require mental alertness and motor coordination.

If you have any concerns or facing side effects due to the medication, consult your doctor. It would help if you tried to tell your doctor of any pre-existing conditions or medications you are using (Kriel, H.H. and Yngve, D., 2019).

What Combination Of Drugs Could You Take Instead?


Taking Gabapentin with some OTC medications that treat allergy and pain relief is considered safe. However, you must check with your doctor before taking any combination of medicines. 

Some common combinations with Gabapentin with OTC medicines can include:

Some common medications you can take with Robaxin include:
